I will give brainliest please help and explain, I forget how to do this.

I need more context then that but if its simply measured thats about an inch

Step-by-step explanation:

1) measure of each ∡ = 120°

2) sum of all exterior angles = 360°

Step-by-step explanation:

1) if this hexagon is 'regular' (meaning all sides and angles have the same measure) then you can divide the total sum (720°) by 6 to get 120°

The formula to find the total sum of interior ∡'s is (n-2)·180 where 'n' is the number of sides

2) the sum of all exterior angles for any polygon is always 360°

none of them really but if it had to be between all of them it would be the second one or b.
